Answer 1

Where jsonObj is the JSONObject which contains some data, By these following code you can get only field names, if u want for column values then you can add further for value for keys.

List listArray = new ArrayList();
    Iterator iter = jsonObj.keys();
    int count=0;
    while(iter.hasNext()){
        listArray.add((String)iter.next());
        count +=1;
    }
    System.out.println(listArray);

output: [projector, video_conference, polycom, lcd, digital_phone, speaker_phone]
